I found this one testing arm but it is reproducible with i686-pc-linux-gnu as
well.

For me
./xgcc -B. -shared ice.o -flto
takes ages because iterative_hash_gimple_type seems to be exponential in time!?

I guess we should try hashing without duplicates or store the hash somewhere...
I cannot reproduce the ICE btw. A patch to fix the slowness would be

Confirmed. (even with the first testcase, I messed things up)
Maybe non-LTO related.

------- Comment #8 from rguenth at gcc dot gnu dot org 2009-08-26 10:54 -------
The issue here is that during linking we do not optimize which triggers the
path in out-of-ssa coalescing that assumes no overlapping life-ranges are
present. Which is obviously not true if we optimized during lto generation.
So this is really a middle-end problem. Honza - what do you suggest to do
here?
